The Other Presidency: Thomas Jefferson and the American Philosophical Society

In The Other Presidency, Patrick Spero resurrects an overlooked but essential part of Thomas Jefferson’s life. For nearly seventeen years, Jefferson served as President of the American Philosophical Society (APS), the nation’s first learned society and one dedicated to promoting new research in the young republic, especially in the sciences. He did so while also serving as Vice President and President of the United States. As Spero shows in this short but important work, Jefferson used his various positions to solidify the Society’s foundation and, in turn, shape the course of American science. 

Through a deep dive into APS Archives and Jefferson’s papers, Spero demonstrates how the Society became a thoroughly Jeffersonian institution—that is, the APS, the largest and most powerful scientific body in the nation, advanced an agenda that comported with Jefferson’s own priorities. While Jefferson juggled affairs of state, he also remained deeply involved in the Society. In fact, the two complemented each other. He helped draft the institution’s first collection development policy, making clear the items and material he thought most important for the nation’s posterity. He also used his international network to introduce European intellectuals to the Society, and he called on these same networks to help build the Society’s collection. Jefferson himself received direct support from the Society to conduct his own research, including funding for an expedition with James Madison, and as President of the United States, he would often call on the APS and its members for advice. In short, Spero shows that Jefferson was integral to the development of the APS—and, perhaps more unexpectedly, the APS and the scientific community it fostered were integral to Jefferson and his vision for the young United States.

A resource for students, history buffs, and Jefferson aficionados, the book includes a chronology of Thomas Jefferson's contributions to the APS, with references to major events in Jefferson's life.
